Disease relevance of Bone Screws

• Histologic study of the bone adjacent to titanium bone screws used for mandibular fracture treatment [1].

High impact information on Bone Screws

• Biomechanical and histomorphometric study on the bone-screw interface of bioactive ceramic-coated titanium screws [2].
• Single crystal alumina for dental implants and bone screws [3].
• In the current study, we investigated whether the systemic administration of alendronate, a third-generation bisphosphonate, suppressed the loosening of screws at the bone-screw interface [4].
• In this work, a metallic plate was fixed to a polyurethane block with either two bone screws, two smooth-surfaced posts, or two novel smooth-surfaced posts with adjustable inclinations [5].
• Improved bone-screw interface with hydroxyapatite coating: an in vivo study of loaded pedicle screws in sheep [6].

Anatomical context of Bone Screws

• Dural reconstruction with fascia, titanium mesh, and bone screws: technical note [7].
• Fracture-luxations of the seventh lumbar vertebrae in two large dogs were stabilised with bone screws and methylmethacrylate [8].
• Three titanium bone screws with preattached pairs of No. 1 polypropylene sutures were placed directly into the medial aspect of each inferior ramus of the pubic bone [9].
• Black particles were observed in the bone and soft tissues around the titanium bone screws, and multinuclear giant cells resembling macrophages were observed near these particles [1].

Associations of Bone Screws with chemical compounds

• Distraction decompression was performed, using cancellous bone screws and methylmethacrylate [10].
• An anchorage system with four pegs each 10 mm in diameter and 20 mm long and an anchorage system with four cancellous bone screws each 6.5 mm in diameter were loaded eccentrically, and both systems prevented distraction of greater than 76 microns when mounted on urethane foam [11].
• For 10 years prior to the availability of the Olecranon Screw described in this article, oblique fixation using a regular Sherman bone screw was employed for displaced fractures (with a suitable fragment) by engaging the anterior ulnar cortex [12].
• To evaluate tissue reaction to cobalt 60 irradiation around implant materials used in maxillofacial surgery, 2.0-mm titanium alloy bone screws and 2.0-mm cylindrical solid hydroxyapatite implants were placed in mandibular bone of rabbits and irradiated with a single 15-Gy dose on the fifth postoperative day [13].
• Pretapped and self-tapping screws in the human midface. Torque measurements and bone screw interface [14].

Gene context of Bone Screws

• OBJECTIVES: Schuhli locking nuts provide a mechanism to lock 4.5-millimeter bone screws to a standard dynamic compression plate (DCP plate) [15].
• A dimensionless set of stress-transfer parameters (STP) was developed to quantify the screw-bone load sharing, enabling a convenient rating to be given of the biomechanical compatibility of practically any given screw design according to the nature of the simulated mechanical interaction [16].
• The CAS technique shows better screw placement without outside bone screw and a very low radiation exposure [17].

Analytical, diagnostic and therapeutic context of Bone Screws

• This is the world of titanium or cobalt-chromium joint designs, bone screws and plates, orthotic limbs, supports and wheelchairs, and futuristic ideas such as miniature video cameras for artificial eyes [18].
